Summary: Infectious diseases caused by bacteria in skin wounds are a significant issue that delays wound healing. The use of wound dressings made from renewable polymers and natural essential oils can overcome these problems. In this study, wound dressings were prepared using carboxymethyl cellulose (CMC)/quaternized starch (MS-Q188) and antimicrobial cinnamon essential oil (CIEO) nanoemulsion. The resulting bionanocomposites were evaluated for their properties. The bionanocomposites showed good tensile properties, but the addition of CIEO nanoemulsion affected their hydrophilicity and barrier properties. Cytotoxicity assays showed that the bionanocomposites were not toxic to cells. The inhibitory effects of CIEO nanoemulsion on various pathogenic microbes were also confirmed.
